What could be a major reason that multi-mode fibers are used instead of single-mode fibers for LANs?
A) higher speed
B) lower cost
C) longer propagation distance
D) lower error rate
E) lower dispersion

Question

Quizplus · Accepted Answer

Multi-mode fibers are generally less expensive than single-mode fibers, which could be a major factor in their use for LANs. While single-mode fibers can transmit signals over longer distances and have lower dispersion and error rates, these factors may not be as crucial in LAN environments where distances are shorter and data may not require the highest level of accuracy. Additionally, multi-mode fibers can support higher speeds than copper cabling, making them a popular choice for LANs.
